c# 判断时间是否在 某一时间段内

1.判断时间是否在某一时间段内

protected bool getTimeSpan(string timeStr)
{ 
    //判断当前时间是否在工作时间段内
    string _strWorkingDayAM = "08:30";//工作时间上午08:30
    string _strWorkingDayPM = "17:30";
    TimeSpan dspWorkingDayAM = DateTime.Parse(_strWorkingDayAM).TimeOfDay;
    TimeSpan dspWorkingDayPM = DateTime.Parse(_strWorkingDayPM).TimeOfDay;

    //string time1 = "2017-2-17 8:10:00";
    DateTime t1 = Convert.ToDateTime(timeStr);

    TimeSpan dspNow = t1.TimeOfDay;
    if (dspNow > dspWorkingDayAM && dspNow < dspWorkingDayPM)
    {
        return true;
    }
    return false;
}

测试

protected string getResult=string.Empty;
        protected void Page_Load(object sender, EventArgs e)
        {
            string time1 = "2017-2-17 9:45:00";
            //DateTime t1 = Convert.ToDateTime(time1);
            bool resultBool = getTimeSpan(time1);
            getResult = Convert.ToString(resultBool);
        }

结果：
